Now your ready to glue down your surround. In the past I've used a pencil to draw around the surround so I would know where to lay my bad of glue. Today I didn't need one cause the surround fit beautifully right up to the basket. Flip the foam over( again having an extra set of hands helps) Lay your bead down don't be skimpy and let the foam settle softly in place.
Apply downward pressure till you see glue coming out around the foam. Do this all the way around your sub. Apply spray as mentioned before in small areas. Always Keeping pressure in front and behind of where your spraying.
I would suggest keeping any and all activator away from the cone. Excess activator can turn these cones white.
